The 10 Words Every Japanese Office Drama Runs On (4 Are “Advanced” on Paper)
Published 2026-07-31
Standard JLPT vocabulary lists file 部下 (subordinate), 上司 (boss), 派遣 (temp work), and 退職 (quitting) under N1 — the top level, one most learners never reach. Japanese office dramas file them under episode one. We counted every word in 7,643 lines of workplace dialogue from a public subtitle corpus, and those four “advanced” words all made the top 10.
That is the quiet lesson of this genre: the vocabulary of Japanese working life is not exotic — it is just taught late. If you ever plan to work in Japan, or simply want to follow a workplace drama without pausing, this list is a head start most textbooks won't give you.
Where do these rankings come from?
Word frequency is counted across 7,643 subtitle lines classified into this genre from JESC, an open research corpus of 2.8 million Japanese TV & film subtitle lines (Pryzant et al. 2018, CC BY-SA 4.0).
The map only lists words that already have a reviewed entry in our library — a frequent word you expect may still be in production, and each new set extends the map.
A few entries are compound words counted under their core component (a student-council compound under its base word, for example), so a count can occasionally sit slightly above the entry ranked before it.
Counts tied to specific franchise titles are excluded or adjusted, and the corpus predates 2018 — so the newest slang of a genre can rank lower than it feels like it should.

The top 10, one by one
meeting / conference · 1,336× in this dialogue set
Where office dramas live. それでは、会議を始めます (“well then, let's begin the meeting”) opens the scene — and any real meeting you will ever sit in.
subordinate (at work) · 1,194× in this dialogue set
An N1-list word; practically, episode-one vocabulary. Its pair is 上司 (#4) — an axis of rank, where 先輩 and 後輩 mark seniority instead.
department manager; general manager · 1,119× in this dialogue set
Doubles as a form of address — characters call out 部長 the way English speakers use a name. One subtlety dramas teach for free: on the phone with another company, you drop the title for your own boss.
boss / superior (at work) · 675× in this dialogue set
The other half of the rank axis, and another N1-list word. You will hear it in the classic complaint 上司が厳しい (“my boss is strict”) — used to talk about your boss, never to their face.
company employee · 583× in this dialogue set
The all-purpose word for a company employee. Watch for the compound 正社員 (permanent employee) — the employment-status distinction that fuels half the genre's storylines.
salary / pay · 522× in this dialogue set
Salary — the word behind payday scenes and the eternal sigh 給料が安い (“the pay is low”). 給料日 (payday) is a small national holiday of the heart.
section manager · 450× in this dialogue set
Section manager — one step below 部長 (#3), and likewise used as a form of address. Japanese org charts come with their own vocabulary, and dramas are a free guided tour of it.
temp-agency work (派遣社員 = temp worker) · 351× in this dialogue set
A whole social storyline in one N1 word — the temp worker vs. permanent employee divide powers entire series. You will hear it as 派遣で働いています (“I work as a temp”).
sales (department); business operations · 341× in this dialogue set
Sales — as a department, a job, and a daily activity. 営業に行ってきます (“I'm off to see clients”) is the standard exit line, and in real business Japanese this word is everywhere.
leaving one's job; retirement (退職する) · 285× in this dialogue set
N1 on paper, practically the season finale: the resignation envelope on the desk. In real life you will meet it on paperwork and in farewell speeches as 退職します (“I'm leaving the company”).
Why this genre pays off
Office dramas are the rare genre where every frequent word transfers directly to real working life — the same top 10 that carries the salaryman's day on screen would serve you in a Tokyo office next year. If your goal is business Japanese, this is the most efficient television you can watch.
